I'm very sorry to hear this. Have you had a case open for this concern? If not, I would be happy to help! Please send us a private message.I have 2019 jeep Cherokee... bought brand new! I have had the same issues with phone favorites disappearing..... I mostly notice it happening after I have connected android auto and then disconnected it! It happens sporadically, and the dealership can't get it to do it for them, so they say there is nothing they can do! Sooo frustrated! And everyone keeps telling me it's my phone! It's not! I have gotten a different (newer phone) not the latest and greatest cause I can't afford thousands of dollars for a new phone after paying for a brand new car! The employees at Chrysler keep telling me they haven't heard of anyone having this issue! Ugh!! Have had the update done, and still didn't fix this issue!
